This section introduces methods on a Connection object for checking the database server statistics and the driver connection.

Each example focuses solely on the method's usage. For a complete code example, please refer to the full example.

stats()

Retrieves database server statistics.

Parameters:

• RequestConfig (Optional): Configuration settings for the request.

Returns:

• Stats: The retrieved server statistics.

Stats stats = client.stats();
System.out.println("CPU usage: " + stats.getCpuUsage() + "%");
System.out.println("Memory usage: " + stats.getMemUsage() + "MB");
System.out.println("Expiration date: " + stats.getExpiredDate());
System.out.println("CPU cores: " + stats.getCpuCores());
System.out.println("Company: " + stats.getCompany());
System.out.println("Server type: " + stats.getServerType());
System.out.println("Version: " + stats.getVersion());

CPU usage: 111.151108%
Memory usage: 10939.929688MB
Expiration date: Thu Dec 26 23:59:59 2024
CPU cores: 80

test()

Tests driver and database server connection.

Parameters:

• RequestConfig (Optional): Configuration settings for the request.

Returns:

• Response: Result of the request.

Response response = client.test();
System.out.println(response.getStatus().getErrorCode());

SUCCESS
